KOREMA® links tradition with innovation Products KOREMA® is one of the leading manufacturers of flexible expansion joints. Expansion joints connect up pipelines. These transition elements compensate for movements and can also act as acoustic and thermal decouplers. The various designs arise from the different movements which need to be absorbed: belt types, U types and a variety of special designs. History The company was founded at its present location in Weiterstadt near Darmstadt, Germany, in 1968. For its time, it was the first specialist company in the world to manufacture novel types...

A sandwich made to measure Expansion joints have a sandwich design. Elastomers and foils are calendered onto high strength substrates and the attachment areas are then vulcanised by means of special adhesives. Depending on the design, the joints have excellent temperature stability and outstanding chemical resistance. Flow liners prevent abrasive media in turbulent flow from damaging the fabric. Tight and stable Elastomers such as Silikon®, Hypalon® and Viton® provide resistance to media attack and improve joint sealing. Externally they act as protection against physical damage and...

General information about KOREMA® expansion joints Connecting pipes KOREMA® expansion joints connect piping systems which convey gaseous or dust laden flue gases at pressures above or below atmospheric pressure. The function of flexible joints is to absorb pipe movements in all directions: - Axial expansion and contraction (linear movement) - Lateral offset (side movement) - Torsion (twisting ) The point of application determines the design The precise design of the expansion joint is determined by its point of application. The basic shapes are round, square and oval. Expansions joints with...

General information Selection guide Required parameters Expansion joint design height Installation height To customise expansion joints to your requirements, we require exact parameters about the media flowing through the expansion joints. The following criteria are relevant: - Medium consistency and properties: whether it contains dust, acid, solvent etc. - Temperatures: internal, external, average and peak values - Operating pressure: above or below atmospheric pressure, pressure peaks, burst pressure, incident design pressure - Flow velocities - Use of guide pipes/flow liners -...

KOREMA belt type ® Expansion joint for large dimensions Various basic designs KOREMA® belt types come in all sizes, even for extremely large duct dimensions. Pre-insulation is also possible in the form of dust protection liners or protection against excess temperatures. Open, prepared joint KOREMA® belt type expansion joints can also be delivered with «open ended joint». The special KOREMA® adhesive for closing joints is also supplied. Preassembled units ready to fit are available complete with the associated steel parts. Fitting is made easier by pre-punching the flange holes. On request,...

Standard at a high level The most common type KOREMA® U type expansion joints are the most frequently installed version. They are also referred to as «flange type» since they are flanged between the ends of two pipes or ducts. Flange design is dependent on the existing plant, customer specifications or the existing steel construction on site. This type also comes with pre-insulation and protection against dust-laden media. Additional elastomeric gaskets ensure drip tightness if the system operates at or below dew point. KOREMA® expansion joint fitted between induced draught fan and stack

KOREMA special designs ® Customised, short turnaround A3 expansion joint with inclined offset flange, food-safe variant with flow sight glass Special shape templates to produce a variety of different expansion joints A35 with varying cross section with SIMIFLON®

SIMIFLON® – for the food and pharmaceutical industries Patented material: SIMIFLON ® Special requirements Materials which are used in food and pharmaceutical production are subject to particularly stringent regulations. On the one hand, they should be completely safe from a physiological aspect. On the other hand, internal components which come into contact with the product must be easily and totally cleanable – when the batch is changed or at every cleaning operation. SIMIFLON ® – the solution To meet these requirements, KOREMA® developed the special material Simiflon®. It is based on the...
